@sujinmkang : qiluo requested in PR 1966 that this new PR be created to facilitate delivery to the 202012 branch. Thanks, |

@dflynn-Nokia Do we still need this PR to be merged? Can you please rebase this PR? |

@sujinmkang Yes, I would like this merged to 202012. I will rebase. |
…vice Tree The warm-reboot and fast-reboot commands currently expect a platform that uses GRUB. Information about the current kernel boot arguments is extracted from the GRUB config file. This commit adds support for platforms that do not use GRUB but rather use Device Tree to define the current kernel boot arguments. Example platform architectures using Device Tree include armhf and arm64. This commit also includes a minor improvement to a similar change made to the soft-reboot command in PR# 1963

The warm-reboot and fast-reboot commands currently expect a platform that uses
GRUB. Information about the current kernel boot arguments is extracted from
the GRUB config file. This commit adds support for platforms that do not use
GRUB but rather use Device Tree to define the current kernel boot arguments.
Example platform architectures using Device Tree include armhf and arm64.
This commit also includes a minor improvement to a similar change made to the
soft-reboot command in PR# 1963
What I did
Fix kexec portion of warm-reboot and fast-reboot commands for the armhf and arm64 platforms
How I did it
Add logic to retrieve kernel boot arguments from the Device Tree rather than from the GRUB config for these platforms
How to verify it
Execute the warm-reboot and fast-reboot commands on an armhf or arm64 platform and confirm that kexec reboots the switch as expected
Previous command output (if the output of a command-line utility has changed)
New command output (if the output of a command-line utility has changed)
